importData of DataStore, Methods Webix Docs
import data from a different datastore
void importData(object source);
Example
$$("listB").data.importData($$("listA"));
Details
Similar to the sync command, but makes one time import only.
The method does not copy the data, so item updates in both widgets will be shared. To fully copy the data from one widget into another one, you need to apply:
$$("listB").parse($$("listA").serialize());
